Petunia plant named ‘KLEPH07145’

ABSTRACT

A new cultivar of  Petunia  particularly characterized by its double, light lemon-colored flowers and its compact, semi-upright growth habit, is disclosed.

Genus and species: Petunia hybrid.

Variety denomination: ‘KLEPH07145’.

BACKGROUND OF THE NEW PLANT

The present invention comprises a new and distinct cultivar of Petunia, botanically known as Petunia hybrid, and hereinafter referred to by the cultivar name ‘KLEPH07145’. ‘KLEPH07145’ was discovered as a seedling resulting from a cross conducted in summer 2004 in Stuttgart, Germany between the female Petunia parent, ‘KLEPH05117’ (U.S. Plant Pat. No. 18,590) and the proprietary male Petunia parent, ‘W 115’ (unpatented). A single plant selection was subsequently chosen for further evaluation and for asexual propagation.

The new cultivar was created in 2004 in Stuttgart, Germany and has been asexually reproduced repeatedly by vegetative cuttings and in-vitro propagation in Stuttgart, Germany over a three-year period (more than 45 generations). ‘KLEPH07145’ has been found to retain its distinctive characteristics through successive asexual propagations.

SUMMARY OF THE INVENTION

The following are the most outstanding and distinguishing characteristics of this new cultivar when grown under normal commercial practices in a greenhouse in Stuttgart, Germany.

-   -   1. Double, light lemon-colored flowers; and     -   2. Compact and semi-upright growth habit.

DESCRIPTION OF THE PHOTOGRAPH

This new Petunia plant is illustrated by the accompanying photograph which shows foliage and a close-up of the mature flower; the colors shown are as true as can be reasonably obtained by conventional photographic procedures. The photograph is of a plant about 5-months old and grown from rooted cuttings in an 11-cm pot under greenhouse (glasshouse) in Stuttgart, Germany under conditions which approximate those generally used in commercial practice.

DESCRIPTION OF THE NEW CULTIVAR

The following detailed descriptions set forth the distinctive characteristics of ‘KLEPH07145’. The data which define these characteristics were collected from asexual reproductions carried out in Stuttgart, Germany. The plant history was taken on 5-month-old plants in 11-cm pots that were pinched once approximately one week after potting and grown in a greenhouse in the spring. The color readings were determined under natural light. Color references are to the RHS Colour Chart of The Royal Horticultural Society of London (RHS) (2001).
